Description
Verfahren zum Auseinandertreiben einer geschlitzten f- zwischen -zwei Treibkörpern gelagerten- Dübelhülse zum Befestigen von Mauerdübeln Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Auseinändertreiben einer geschlitzten, zwischen zwei Treibkörpern gelagerten Dübelhülse zum Befestigen von Mauerdübeln.Method for driving apart a slotted f- between -two Propellers mounted dowel sleeve for fastening wall dowels The invention relates to a method and a device for driving apart a slotted, Dowel sleeve mounted between two drifts for fastening wall dowels.
Es ist bekannt, daß Dübelhülsen im Mauerwerk lediglich durch Auseinandertreiben befestigt werden, ohne die sonst üblichen Bindemittel, wie Gips, Zement, anzuwenden. Es ist ferner bekannt, als Treibkörper verjüngte, auf der Befestigungsschraube sitzende Stücke zum Spreizen der Dübelhülse zu benutzen. Bei . schlechtem Mauerwerk versagt jedoch das einfache Auseinanderspreizen der Hülse mit kegelig verjüngten Treibkörpern. Die Hülse liegt dann also nur in einer ringförmigen, schmalen Fläche an dem Mauerwerk an (vgl. die Stelle a in Abb. i, die einen Dübel bekannter Form zeigt).It is known that dowel sleeves in masonry only by being driven apart can be attached without using the usual binders such as plaster of paris, cement. It is also known as a propulsion body that is tapered and seated on the fastening screw Use pieces to spread the dowel sleeve. At . bad masonry fails however, the simple spreading of the sleeve with conically tapered propellants. The sleeve is then only in an annular, narrow area on the masonry (see point a in Fig. i, which shows a dowel of known shape).
Gemäß der Erfindung, die auf der beiliegenden Zeichnung veranschaulicht ist, sind die Treibkörper mit einer ringförmigen Hohlkehle g versehen. Hierdurch wird bei der Formänderung der Dübelhülse ein vollständiges Anschmiegen, ein Einkrallen in das umgebende Mauerwerk erzielt. Die Dübelhülse wird an den Enden zunächst umgebördelt und geweitet, dann besonders am hinteren Ende lotrecht zu ihrer Achse stark auseinandergetrieben. Die Dübelhülse b (Abb. 2 oder 6) wird zwischen Treibkörpern d, f (Abb. 3) eingespannt, welche Hohlkehlen g besitzen. Werden die Treibkörper einander genähert, so muß die Dübelhülse b mit ihren -äußeren Rändern zunächst ausweichen, und die Enden werden sich umbördeln, wobei sie eich in das umgebende Mauerwerk eingraben (Abb. q.). Die Aufbördelung ist nur begrenzt durch den Widerstand des sie umgebenden Mauerwerkes. Werden die beiden Treibkörper d und f einander noch mehr genähert, so wird die Hülse b lotrecht zu ihrer Achse aufgeweitet (Abb.5). Der äußere Durchmesser der Hülse b -nimmt je: nach--Maßgabe des Eindringens des hinteren Treibkörpers erheblich zu, so daß also eine allseitige feste Anlagerung an das umgebende Mauerwerk erfolgt.According to the invention, which is illustrated in the accompanying drawing, the propulsion bodies are provided with an annular groove g. As a result, when the dowel sleeve changes shape, it snuggles completely into the surrounding masonry. The dowel sleeve is first crimped and widened at the ends, then, especially at the rear end, it is strongly driven apart perpendicular to its axis. The dowel sleeve b (Fig. 2 or 6) is clamped between propellants d, f (Fig. 3), which have fillets g. If the propellants come closer to one another, the dowel sleeve b must first give way with its outer edges, and the ends will bead around, digging into the surrounding masonry (Fig. Q.). The flanging is only limited by the resistance of the surrounding masonry. If the two propellants d and f are brought closer to each other, the sleeve b is widened perpendicular to its axis (Fig.5). The outer diameter of the sleeve b -increases depending: - depending on the penetration of the rear propellant body, so that there is a solid attachment to the surrounding masonry on all sides.
